BICYCLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 597,403, dated January 1S, 1898.

Application filed November 12,1896. Serial No. 611,822. (No model.)

To @Z3 whom it may concern,.-

Be it known that l, CARL EIOKEMEYER, acitizen of the United States, residing at Yonkers, in the county of Vestchester and State of New York, have invented certain new and useful Improvements in Brakes for Bicycles, of which the following is a specification.

This invention relates to an improved brake for bicycles, which is especially designed to be used in connection with bicycles of that class in which the handle-bars are supported on a rearwardly-extending tube of the spindie of the front wheel and extended from said tube in forward direction, said brake being so arranged as to be out of the way and readily operated by means of a brake-lever that is within convenient `reach of the handle-bars and the invention consists of a brake for bicycles the brake-rod of which is arranged in the spindle of the front fork and actuated by a brake-lever fulcrunied to an adjustable standard on the bearing of the front spindle. The brake-shoe is attached at the lower end of the brake-rod and supported in raised position by a U-shaped spring, the recessed front end of which engages the lower recessed part of the brake-rod. The brake-shoe has upwardly-bent projections at its rear end that engage the brake-spring and prevent it from turning independently of the fork-spindle, as will be fully described hereinafter, and finally pointed out in the claim.

In the accompanying drawings, Figure l represents a side elevation of the 'upper portion of a bicycle with my improved brake applied thereto. Fi g. 2 is a vertical central section thrcn gh the spindle of the front fork and the brake. Fig. 3 is a side elevation of a brake shown as applied to a modified construction cf bicycle; and Fig. 4 is a detail horizontal section on line 4 4, Fig. 2.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the spindle of the front fork of my improved bicycle, which spindle is supported in the head B of the frame, which head carries at its front part a socket b. In the socketb is adj ustably supported an upright standard C by means of a set-screw ZJ. To the upper end of the standard C is applied a brake-lever C', the front end of which is provided with a handle C2, while the flattened or enlarged rear end acts on the upper end of a brake-rod E,which projects above the spindle A of the front fork, as shown in Fig. l. The front arm of the fulcruined brake-lever C is supported on a iiat spring O3, that is attached to the upper end of the standard (l, its free end pressing the brake -lever in upward direction. To Vthe crown of the fork D is attached a fla-t U- shaped brake-spring E2, which is provided at its upper end with a downwardly-bent shoulder or offset, through which passes the fastelling-screw c2, as shown in Figs. l and 2. The lower part of the U-shaped spring E2 is extended in forward direction and provided with a recess in its iront end. The brakerod E is made in two sections, alower section e', extending at right angles from the braheshoe F, and the upper section that is guided in a screw-plug e at the upper end vof the hollow spindle A. The sections of the brakerod E are connected by a sleeve E', to which the upper section is attached by a clampingscrew e, The sleeve E slides in the crown of the'forl; D and in the hollow spindle of the same, as shown in Fig. 2. The recessed front endof the brake-spring E2 is located between the lower end of the sleeve Ff and the bralre-shoe and so arranged as to engage side recesses on the section e next adjacent to the brake-shoe, as shown in Fig. Ll. bralre-shoe F has forked projections e at its rear end, which engage the spring FF, so as to prevent the brakeshoe F from turning on the axis of the brake-rod and retain it thereby always in the same direction as the wheeltire.

An aperture eX is arranged in the head B for giving access to `the clamping-screw e, so that the upper end of the brake-rod E can be adjusted higher or lower in the sleeve E. The lower end of the fork-spindle A is slotted for permitting the clampingscrew e to play up and down in said slot, when the bralie-rod E, with its sleeve E', is lowered by the pressure of the brake-lever G.

In the modified construction shown in Fig. 3 the upright standard C, to which the brakelever C is fulcru med, is arranged in a socket b on a horizontal tube B', which connects the head B for the spindle A of the front forli with a support G for a working spindle G',
